Complete Crawl Space Solutions and Waterproofing in Midland

We design sealed crawl spaces that control water, humidity, and energy loss in West Texas conditions. Every project starts with a moisture assessment and ends with documented results and a transferable warranty.

Crawl Space Waterproofing

Recurring dampness, musty odors, or cupped floors point to moisture intrusion. Our waterproofing systems combine interior perimeter drains, sealed sumps, and wall/ground liners to stop vapor and water. We use Class I vapor retarders (ASTM E1745) and dimpled drainage matting to channel water to a sealed basin with check valve and battery backup. Installations follow IRC R408.3 for unvented crawl spaces. The result: dry, stable conditions that protect wood framing and improve comfort. Learn more about our Crawl Space Waterproofing services.

Crawl Space Vapor Barrier Installation

Soil vapor rises year-round in the Permian Basin. We install reinforced liners (StegoCrawl or equivalent) in 12–20 mil thickness, overlapping seams 6 inches, fully taping with butyl/acrylic tape, and wrapping/ sealing piers before the ground liner. The barrier is mechanically fastened to walls with termination bar and masonry fasteners for a permanent seal. Expect cleaner air, less odor, and lower humidity that protects insulation and ducts. Learn more about our Crawl Space Vapor Barrier Installation services.

Crawl Space Dehumidifier Installation

Even with a sealed liner, seasonal humidity can spike. We size and install high-efficiency dehumidifiers (70–100 pints/day) with a dedicated GFCI outlet per NEC and a condensate drain to the exterior or sealed sump with an air gap. We target 45–55% RH year-round and place hygrometers for remote monitoring. This stops mold growth, protects hardwoods, and eliminates sweaty HVAC ducts. Our team also sets maintenance reminders and offers annual service plans. Learn more about our Crawl Space Dehumidifier Installation services.

Crawl Space Drainage System Installation

Standing water undermines encapsulation. We install interior French drains using PVC drain tile, gravel, and filter fabric around the crawl space perimeter. Water flows to a sealed sump basin with a quiet, high-lift pump and battery backup for power outages. Before encapsulating, we verify performance with a moisture meter and inspection camera. This step protects your investment and is vital in areas with clay/caliche soils and wind-driven rain. Learn more about our Crawl Space Drainage System Installation services.

Crawl Space Insulation Installation

Insulating walls and rim joists turns a damp crawl into a conditioned, energy-smart space. We offer closed cell spray foam on walls and rim joists or rigid foam board solutions (EPS/XPS/polyiso), combined with rim-joist air sealing. We leave a termite inspection gap where required by pest pros. Expect quieter floors, reduced drafts, and lower utility costs. Our SPFA-certified crews follow best practices to prevent cold floors and condensation. Learn more about our Crawl Space Insulation Installation services.

Why Homeowners Choose Us for Crawl Space Encapsulation in Midland, TX

Odessa Crawl Space has helped thousands of West Texas homeowners fix wet, musty, and inefficient crawl spaces since 2009. We pair building-science expertise with proven materials to deliver durable, code-compliant results. You get clear communication, photo documentation, and warranties that protect your investment.

Certified Expertise and Code Compliance

Encapsulating correctly means following the rules that keep your home safe. We build to IRC R408.3 unvented crawl space requirements, including vent closure, conditioned air or dehumidification, and ground/wall vapor control. For liners, we specify Class I vapor retarders meeting ASTM E1745 and use termination bars for a permanent seal.

When projects involve mold or utilities, we bring the right licenses to the table: TDLR Mold Remediation Company/Contractor (as required for ≥25 sq ft), TSBPE-licensed plumber for sump/discharge piping, and a TDLR-licensed electrician for dedicated, GFCI-protected circuits in the crawl. For pre-1978 homes, we operate as an EPA Lead-Safe RRP certified firm.

Our team holds IICRC WRT/AMRT, SPFA PCP, and BPI certifications, and we stay active with the Basement Health Association, SPFA, ICAA, TPCA, and InterNACHI for continuing education.

Safety-First Process and Professional Equipment

Your home and family come first. Crews follow OSHA confined-space and PPE protocols with respirators, Tyvek suits, and knee protection. We control dust using HEPA vacuums and negative air machines during cleaning or mold remediation to meet ANSI/IICRC S520 guidelines.

We verify moisture sources using moisture meters, thermo-hygrometers, and inspection cameras. A manometer helps diagnose pressure imbalances. For liners, we use utility knives, seam rollers, butyl/acrylic tapes, and rotary hammers to fasten termination bars cleanly. Every installation includes a final RH reading and photo report so you can see the workmanship.

Built for Midland–Odessa Conditions

West Texas brings dramatic humidity swings, caliche soils, and wind-driven dust. We design for that reality: drainage to a sealed basin with check valve and battery backup, taped and sealed seams overlapped 6 inches, and protected traffic paths with matting for service access. Where appropriate, we insulate walls or rim joists with closed cell spray foam or rigid foam to stop duct sweating and cold floors.

Case in point: In August 2024, we sealed a 1,720 sq ft crawl space in 79705 near Grassland Estates using a 20 mil liner, interior drain to sump, and a 90-pint/day dehumidifier. RH dropped from 72% to 50% within 48 hours, eliminating musty odors and stabilizing hardwood floors.

Transparent Pricing, Financing, and Real Warranties

You’ll know the scope, materials, and cost before work starts - including whether drainage is needed before encapsulation. We offer financing options, phased solutions when budgets require, and written warranties (liner and tape system, sump components, and dehumidifier). Annual maintenance and humidity monitoring keep performance on track.

Frequently Asked Questions

What is crawl space encapsulation and what’s included?

Encapsulation seals your crawl from earth and outside air to control moisture and improve air quality. Typical scope includes debris removal, Class I vapor barrier on ground and walls, sealed seams and piers, vent sealing, insulated/air-sealed access door, drainage to a sealed sump if needed, and either a dehumidifier or conditioned air supply. We document humidity before/after and meet IRC R408.3. It’s a durable system, not just plastic on the floor.

Do I need drainage or a sump pump before encapsulating?

If water enters during storms or irrigation cycles, drainage comes first. We install an interior French drain with PVC drain tile, gravel, and filter fabric that directs water to a sealed sump basin with a check valve and optional battery backup. Once bulk water is managed, we encapsulate. Skipping this step risks trapping water under the liner. Our inspection includes moisture mapping to confirm whether drainage is required.

Should crawl space vents be closed and a dehumidifier installed?

Yes - West Texas brings humidity swings that cause condensation, mold, and duct sweating. Under IRC R408.3, unvented crawls must be conditioned. We either add a small supply (about 1 CFM per 50 sq ft) from the HVAC or install a 70–100 pint/day dehumidifier with a dedicated GFCI outlet and condensate drain. We target 45–55% RH year-round for stability and healthy indoor air.

What vapor barrier thickness and materials do you use?

We use reinforced polyethylene liners that meet ASTM E1745 (Class I vapor retarder), typically 12–20 mil. In Midland, we recommend 15–20 mil for durability and service traffic. Seams are overlapped 6 inches and fully taped using butyl/acrylic tapes. We wrap and seal piers first, then mechanically fasten the wall liner with termination bar and masonry anchors for a permanent seal.

How much does crawl space encapsulation cost near Midland?

Costs vary with size, access, drainage needs, and liner/dehumidifier selections. A typical Midland home ranges from a few thousand dollars for a straightforward liner to more for systems with interior drains, sump pumps, and high-capacity dehumidification. We provide a detailed written estimate with options, warranty terms, and financing for Crawl Space Encapsulation Midland TX projects after inspection.

Is spray foam good for crawl space walls and rim joists?

Closed cell spray foam is excellent on walls and rim joists in a sealed crawl. It air-seals, insulates, and resists moisture, helping stop duct sweating and cold floors. In some situations, rigid foam boards (EPS/XPS/polyiso) are preferred for accessibility or termite inspection strips. We’ll recommend the best approach for your crawl based on access, code, and budget.

Do you need a permit to encapsulate a crawl space in Texas?

Requirements vary by jurisdiction. We follow IRC R408.3 for unvented crawls and coordinate with local officials if permits or inspections apply. When scope includes plumbing/electrical tie-ins, we use TSBPE-licensed plumbers and TDLR-licensed electricians. For mold areas ≥25 sq ft, TDLR mold rules apply. Pre-1978 homes are handled under EPA Lead-Safe RRP practices.

How long does a crawl space encapsulation take and how long does it last?

Most Midland projects take 2–4 days depending on size, access, and drainage work. With proper materials (Class I liner, sealed seams, termination bar) and humidity control, systems commonly last 15–20 years or more. Our maintenance plans include annual inspections, filter changes, and RH checks to keep performance on target.

Will encapsulation help with musty odors and allergies?

Yes. Encapsulation and humidity control reduce mold growth, soil gases, and dust, which often improves odors and indoor air quality. We’ve seen odor reduction within days after sealing and stabilizing RH near 50%. Where growth is present, we follow ANSI/IICRC S520 remediation standards before installing liners and dehumidifiers for a clean, healthy result.
